◆ solve_magnetic_field()

VectorField3D num::MagneticSolver::solve_magnetic_field ( const VectorField3D &  J,
double  tol = 1e-6,
int  max_iter = 500 
)
static

Solve for static magnetic field B given current density J. Solves ∆A = −μ₀J (Coulomb gauge, Dirichlet A=0) via three CG solves, then returns B = ∇×A.
